Video output signals and servo reference signal

This section explains how the output signals and servo reference signal are selected.

External synchronization of video output signals

The video output signals are output in synchronization with the REF VIDEO input signal or video input signal. As shown in the figure below, this signal is selected in accordance with the setup menu settings, VTR mode and availability of the video input signal.

<Notes>

Synchronization is determined as follows depending on the availability of the REF VIDEO input signal when “BB”, “CB100” or “CB75” has been selected as the setup menu No. 600 (INT SG) setting.

O When the REF VIDEO input signal is available: Synchronization with the REF VIDEO input signal

O When the REF VIDEO input signal is not available: Internal synchronization
